Enter the hole radius (ft) and the hole depth (ft) into the Hole Size Calculator. The calculator will evaluate the Hole Size.

## Hole Size Formula

The following two example problems outline the steps and information needed to calculate the Hole Size.

**HS = pi*hr^2*hd**

Variables:

- HS is the Hole Size (ft^3)
- hr is the hole radius (ft)
- hd is the hole depth (ft)

## How to Calculate Hole Size?

The following steps outline how to calculate the Hole Size.

- First, determine the hole radius (ft).
- Next, determine the hole depth (ft).
- Next, gather the formula from above = HS = pi*hr^2*hd.
- Finally, calculate the Hole Size.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

hole radius (ft) = 3

hole depth (ft) = 10

HS = pi*hr^2*hd** **= ?
